A method for screening Rosa accessions for their host suitability to Pratylenchus penetrans was developed. The best conditions were obtained in growth chambers with plants grown in sand, inoculated with 250 P.penetrans per 50 cm3 pot and fertilised weekly with 0.75 g/dm3 soluble fertiliser (containing 20% N, 20% P2O5, 20% K2O and balanced trace elements). Fifty days after nematode inoculation, these conditions permitted greater nematode multiplication than any other combination tested and also allowed good host development. When used for the screening of 21 Rosa accessions, these conditions revealed a large variation in host suitability. Least multiplication (Pf/Pi) was observed on R. virginiana (1.36) but this did not differ significantly from that on R. multiflora (2.87). The greatest Pf/Pi was on R. canina cv. Superba but this did not differ significantly from that on R. canina cv. Pollmeriana. The correlation of Pf/Pi with the nematode population and the number of eggs within the roots was significant; the percentage of nematodes outside roots was negatively correlated with Pf/Pi. The intermediate host status of R. corymbifera cv. Laxa, one of the most common rootstocks, was confirmed. Differences in host status became statistically significant when intra-accession variation was observed with a larger number of plants.
